Media specifications

Paper designed for use with xerographic copiers should provide satisfactory print quality and feed reliability. Other types of media may be suitable. It is recommended that users test any particular brand for suitability to their applications. Refer to the printer User's Guide for additional media specifications.

Paper

Follow the media guidelines below for successful printing:

• Rough, highly textured, limp, or pre-curled papers will result in lower print quality and more frequent paper

feed failures.

• Colored papers must be able to withstand 190° C (374° F) fusing temperature.

• Preprinted forms and letterheads must be able to withstand 190° C (374° F) fusing temperature and should

be selected using guidelines found in the printer User’s Guide. The chemical process used in preprinting

may render some papers unsuitable for use.

• Unsuitable papers include: – Multi-part forms and documents – Chemically treated papers; coated – Synthetic and thermal papers – A5 paper less than 80 g/m – Recycled paper less than 75 g/m – Preprinted papers requiring a high degree of registration. – Recycled paper less than 80 g/m

(21 lb)

(20 lb)

(21 lb) may cause unacceptable results.

Envelopes

All envelopes should be new, unused, and without package damage.

•

• Envelopes with excessive curl or twist exceeding 6 mm, those stuck together, those with bent corners or

nicked edges, or those that interlock should not be used.

• Minimum weight: 60 g/m2 (16 lb.)

• The following envelopes should not be used:

• Envelopes with windows, holes, perforations, cutouts, or deep embossing

• Envelopes with metal clasps, string ties, or metal folding bars

• Envelopes with exposed flap adhesive when the flap is in the closed position.

• For best results, printing on new 90 g/m2 (24 lb.) sulfite or 25% cotton bond envelopes is recommended.

• Under high humidity conditions (over 60%), envelopes may seal during printing.

Transparencies

•

Use letter or A4-size transparencies for color laser printers only.

• See Ordering Information for the recommended transparencies for the Lexmark C734/C736 laser printers.

• Do not use inkjet transparencies.

Labels

Labels should be selected using guidelines found in the User's Guide or the Card Stock and Label Guide, and

tested for acceptability.

Using recycled paper and other office papers

Recycled office paper produced specifically for use in laser (electrophotographic) printers may be used in your printer. However, no blanket statement can be made that all recycled paper will feed well.

Generally, the following property guidelines apply to recycled paper.

• Low moisture content (4–5%)

• Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)

Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and

much rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to work very well in laser printers, despite surface texture. Before using these types of paper, consult your paper supplier.

• Suitable sheet-to-sheet coefficient of friction (0.4–0.6)

• Sufficient bending resistance in the direction of feed

Recycled paper, paper of lower weight (<60 g/m paper that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is required for reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing, consult your paper supplier. Remember that these are general guidelines only and that paper meeting these guidelines may still cause paper feeding problems in any laser printer (for example, if the paper curls excessively under normal printing conditions).

Paper guidelines

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating new paper stock.

Weight—The printer can automatically feed paper weights from 60 to 162l7 g/m Paper lighter than 60 g/m performance, use 75 g/m we recommend 90 g/m

Note: Duplex is supported only for 63 g/m Curl—Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl

can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding problems.

Smoothness—Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield points; however, smoothness between 150 and 200 Sheffield points produces the best print quality.

Moisture content—The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly. Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that can degrade its performance.

(24 lb) or heavier paper.

–170 g/m2 (17 lb–45 lb bond) paper.

Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. Extend the time several days if the storage or transportation environment is very different from the printer environment. Thick paper may also require a longer conditioning period.

Grain directio n—Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of the paper, or grain short, running the width of the paper. For 60 to 135 g/m bond) paper, grain long paper is recommended. For papers heavier than 135 g/m

Fiber content—Most high-quality xerographic paper is made from 100% chemically treated pulped wood. This content provides the paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing fibers such as cotton can negatively affect paper handling.

, grain short is recommended.

Unacce p tab l e p aper

The following paper types are not recommended for use with the printer:

• Chemically treated papers used to make copies without carbon paper, also known as carbonless papers,

carbonless copy paper (CCP), or no carbon required (NCR) paper

• Preprinted papers with chemicals that may contaminate the printer

• Preprinted papers that can be affected by the temperature in the printer fuser

• Preprinted papers that require a registration (the precise print location on the page) greater than ±2.3 mm

(±0.9 in.), such as optical character recognition (OCR) forms Note: In some cases, registration can be adjusted with a software application to successfully print on these forms.

• Coated papers (erasable bond), synthetic papers, thermal papers

• Rough-edged, rough or heavily textured surface papers, or curled papers

• Recycled papers that fail EN12281:2002 (European)

• Paper weighing less than 60 g/m

(16 lb)

• Multiple-part forms or documents

Selecting paper

Using appropriate paper prevents jams and helps ensure trouble-free printing.

To help avoid jams and poor print quality:

• Always use new, undamaged paper.

• Before loading paper, know the recommended print side of the paper. This information is usually indicated

on the paper package.

• Do not use paper that has been cut or trimmed by hand.

• Do not mix paper sizes, types, or weights in the same source; mixing results in jams.

• Do not use coated papers unless they are specifically designed for electrophotographic printing.

Selecting preprinted forms and letterhead

Use these guidelines when selecting preprinted forms and letterhead:

• Use grain long for 60 to 90 g/m

(16 to 20 lb) weight paper.

• Use only forms and letterhead printed using an offset lithographic or engraved printing process.

• Avoid papers with rough or heavily textured surfaces.

Use papers printed with heat-resistant inks designed for use in xerographic copiers. The ink must be able to withstand temperatures up to 190°C (374°F) without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner. Inks that are oxidation-set or oil-based generally meet these requirements; latex inks might not. When in doubt, contact the paper supplier.

Preprinted papers such as letterhead must be able to withstand temperatures up to 190°C (374°F) without melting or releasing hazardous emissions.

Storing paper

Use these paper storage guidelines to help avoid jams and uneven print quality:

• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most

label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between 40 and 60%.

• Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.

• Store individual packages on a flat surface.

• Do not store anything on top of individual paper packages.
